Question

what is period in the periodic table? how do atomic structure change in the period with an increase in atomic number​

Answer 1

Answer:

see bellow

Explanation:

horizontal rows of elements in a periodic table are called periods

The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.

hope it helps u ....,

Answer 2

The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
